Install Ace for Linux

First: Download acepackage, use ace-5.8.tar.gz here, other: http://download.dre.vanderbilt.edu/previous_versions/

Only Ace is installed here, and other packages are not involved.

1. Decompress ace-5.8.tar.gz, tar-xvf ACE-5.8.tar.gz in the directory $ home/ace, and generate the directory ace_wrappers under the current directory. In my Environment: $ home/ace ==/ home/worker/ace

2. Set the ace_root environment variable: (you can set it in/etc/profile (I will set it here), or in. bash_profile under my home directory)

Ace_root =/home/worker/ACE/ace_wrappers
Export ace_root
2. Create two file links for different versions:
In the $ ace_root/ace directory:
Ln-s config-linux.h config. h
Under the $ ace_root/include/makeinclude/directory:
Ln-s platform_linux.gnu platform_macros.gnu
3. Set the environment variable LD_LIBRARY_PATH:
LD_LIBRARY_PATH = $ ace_root/lib: $ LD_LIBRARY_PATH
Export LD_LIBRARY_PATH
(Supplement: note that $ ace_root/lib is not $ ace_root/ace. Many websites write the latter. It seems wrong, at least I didn't compile it)

4. Create the directory build and mkdir build in the directory $ ace_root.

Go to the build directory and run the configuration script ../configure [Options].

Common options include cxxflags =-O3 -- disable-Debug -- disable-ace-examples -- disable-ace-tests -- without-tao.

Supplement: If you want to set the installation path (installed in/usr/local by default), you can add the parameter -- prefix [installation path].

That is: ../configure -- prefix =/usr/local/ace cxxflags =-O3 -- disable-Debug -- disable-ace-examples -- disable-ace-tests -- without-Tao

5. Compile #> make

In this process, some header files may not be found. You need to run the relevant commands to install them. The error I encountered is that the OpenSSL header files do not exist, and all the development packages that require libopenssl Installation

Zypper search * OpenSSL * is used to find all OpenSSL packages and select the required packages for installation. Here libopenssl-devel is required.

Zypper install libopenssl-devel (suselinux is used here, all of which use this command,

Use different commands for other versions, such as centos fedora: Yum search * OpenSSL * Yum install libopenssl-devel)

6. Installation #> make install (Supplement: If installation is performed, the original $ ace_root can be changed to the installed path)

Use epoll in ace5.5:
Ace_wrappers/ACE/config-linux.h, add a line: # define ace_has_event_poll
Add-dace_has_event_poll To The makefile of the application and re-make the application. OK. (Fix: Just add a line in ace_wrappers/ACE/config-linux.h: # define ace_has_event_poll, no need to add-dace_has_event_poll to each application)

Note: many functions in Ace are not compiled by default, such as epoll and fastmemcpy. To use these functions, you must modify config. h file, add the corresponding macro to recompile the ace.

If you want to use the msvc Standard C ++ header, you need to add the definition in ACE/config. h:
# Define ace_has_standard_cpp_library 1
Add the config. h file content as follows:
# Define ace_has_standard_cpp_library 1 // use the standard C ++ Header
# Define ace_no_inline 1 // reduce the size of LIB and exe without using the internal connection Function

7. Test.

# Include <ACE/log_msg.h>
# Include <ACE/OS _main.h>

Using namespace STD;

Int ace_tmain (INT argc, ace_tchar * argv [])
{
Ace_debug (lm_debug, ace_text ("Hello World !")));
Return 0;
}

Compile: G ++-I/usr/local/ACE/include-O0-G3-wall-C-fmessage-length = 0-MMD-MP-MF "helloworld. d "-MT" helloworld. d "-o" demo. O "" demo. CPP"

Link: G ++-I/usr/local/ACE/include-L/usr/local/ACE/lib-role-LRT-lpthread-o "acetest" demo. o

Run:./acetest (Supplement: the LD_LIBRARY_PATH directory at this time must point to the lib directory of ACE, Which is/usr/local/ACE/LIB; otherwise, an error occurs.

Output after successful execution: Hello world!
